...
Stuff purchased for testing:
...
SDR radio dongle
misc connectors
...
Next steps:
- install and run RTL-SDR dongle on Mac with whip antenna, check things out
- construct coax alternating antenna, see if that increases range
- use dump1090 utility to track planes in real time.
- Construct KMZ files for visualization in Google Earth
- Construct zero-wind-speed contrail estimator
- Fold in winds aloft data, real-time or historical, to predict contrail diffusion.
- Create masked-off region in alt-az coordinates, then convert to RA-Dec exclusion area
- make test installation for Pachon.
